Production and Characterization of Handmade Paper from Mango (Mangifera Indica l.) Seed Coat and Pulp Fibers

Objective: This study aimed to produce handmade paper from fibers of the seed coat and pulp of mango (Mangifera indica L.), Bacuri variety, evaluating its physico-mechanical properties and viability as a sustainable alternative for valorization of agroindustrial waste. Theoretical Framework: The methodology included specimen collection, fruit treatment with sodium hypochlorite disinfection (2.5%), alkaline fiber extraction with NaOH (10-20%), followed by handmade paper production and characterization of physico-mechanical properties according to TAPPI standards for grammage (T410), thickness (T411), and tensile strength (T494). Method: The methodology adopted for this research comprises [concisely describe the study design, including approach, participants, instruments, procedures, etc.]. Data collection was carried out through [explain the specific methods used, such as interviews, questionnaires, observations, among others]. Results and Discussion: Results showed fiber extraction yields of 18.94% (pulp) and 6.59% (seed coat), with paper properties comparable to conventional products: grammage of 230.33 g/m², thickness of 0.23 mm, and tensile strength of 15.44 N. The discussion highlighted the physical and mechanical characteristics of the produced paper in comparison with literature. Research Implications: Results demonstrate potential applications in packaging and artisanal stationery, directly contributing to Sustainable Development Goals (SDGs) 9 (Industry, Innovation and Infrastructure), 11 (Sustainable Cities and Communities), and 12 (Responsible Consumption and Production) by promoting circular economy and reducing environmental impacts in mango-producing regions. Originality/Value: This study innovates by integrally utilizing specific mango residues, offering a technical and sustainable solution for small producers. Its value is amplified by alignment with regional bioeconomy and contribution to multiple SDGs, demonstrating how applied research can generate positive environmental, social and economic impacts.
